Gift Aid
Another 25p for every eligible pound. Worked out for you.
BID collects the declarations, applies HMRC's split rule to every winning bid and hands you a Charities Online schedule at the end of the night. No spreadsheets, no guesswork.
Reclaimed on every eligible donated pound
All a bidder adds: address and postcode
To generate the HMRC claim file
How it works, start to claim
- 01
The declaration is collected as they register
Bidders register with name and email. Tick the Gift Aid box and two extra fields appear: house name or number, and postcode. That's all HMRC needs. We timestamp the declaration and store the exact wording version they agreed to.
- 02
The split rule is applied per lot
HMRC only allows Gift Aid on the donated element of an auction purchase, the amount paid above the lot's market value. You enter a market value when you build the lot; BID does the subtraction on every winning bid automatically.
- 03
Eligible lots are flagged, ineligible ones are excluded
Mark a lot as Gift Aid eligible in the CMS and it enters the calculation. Money-can't-buy lots with no commercial equivalent, and anything the winner didn't declare on, are left out, so nothing goes into your claim that shouldn't.
- 04
Generate the claim file in one click
Open the Gift Aid tab after the event and hit export. You get a CSV in HMRC's Charities Online schedule format, with names split into first and last, addresses, donation dates and the claimable amount per line.
- 05
Upload it to HMRC and claim
Sign in to Charities Online with your Government Gateway details, attach the schedule to your Gift Aid repayment claim and submit. Repayments typically arrive within a few weeks.
The maths
A £1,000 hammer on a £400 lot raises £1,150.
- Winning bid (hammer price)
- £1,000.00
- Market value of the lot
- − £400.00
- Donated element (claimable)
- = £600.00
- Gift Aid at 25% of the donation
- + £150.00
Formula: claimable donation = hammer price − market value. Gift Aid = donation × (20 ÷ 80), which is 25% at the current basic rate. BID runs this on every eligible winning bid and totals it for the event.
The rules we apply for you
- The winner must be a UK taxpayer and must have made a Gift Aid declaration.
- Only the amount paid above the lot's market value can be claimed on.
- The lot must be commercially available so a genuine market value exists. Unique, money-can't-buy lots generally cannot be split this way.
- The winner must know the market value before bidding, so BID shows it on eligible lots.
- You need the winner's home address (house name or number, plus postcode) on file.
- Claims must normally be made within four years of the end of the accounting period.
The declaration your bidders agree to
“I want to Gift Aid my donation and any donations I make in the future or have made in the past 4 years to this charity. I am a UK taxpayer and understand that if I pay less Income Tax and/or Capital Gains Tax than the amount of Gift Aid claimed on all my donations in that tax year it is my responsibility to pay any difference.”
Stored with a timestamp and a wording version against every bidder, so your claim is auditable.
The file you send to HMRC
One row per eligible winning bid, in the exact column order of the HMRC Charities Online Gift Aid schedule. Download it, attach it to your repayment claim, submit.

Amounts shown are the claimable donated element, not the hammer price. Gift Aid guidance changes from time to time. BID gives you the numbers and the file, but your charity remains responsible for the claim it submits.
